Juniper EX2200 Hardware Guide

•
On EX6200 and EX8200 switches, the network ports are numbered from left to right
on each line card. On line cards that have two rows of ports, the ports on the top row
start with 0 followed by the remaining even-numbered ports, and the ports on the
bottom row start with 1 followed by the remaining odd-numbered ports.
•
Uplink ports on an SRE module in an EX6200 switch are labeled from left to right,
starting with 0.
Logical Part of an Interface Name
The logical unit part of the interface name corresponds to the logical unit number, which
can be a number from 0 through 16384. In the virtual part of the name, a period (.)
separates the port and logical unit numbers: type-fpc/pic/port.logical-unit-number. For
example, if you issue the show ethernet-switching interfaces command on a system with
a default VLAN, the resulting display shows the logical interfaces associated with the
VLAN:
Interface State VLAN members Blocking
ge-0/0/0.0 down remote-analyzer unblocked
ge-0/0/1.0 down default unblocked
ge-0/0/10.0 down default unblocked
Wildcard Characters in Interface Names
In the show interfaces and clear interfaces commands, you can use wildcard characters
in the interface-name option to specify groups of interface names without having to type
each name individually. You must enclose all wildcard characters except the asterisk (*)
in quotation marks (" ").

Understanding Aggregated Ethernet Interfaces and LACP
IEEE 802.3ad link aggregation enables you to group Ethernet interfaces to form a single
link layer interface, also known as a link aggregation group (LAG) or bundle.
Aggregating multiple links between physical interfaces creates a single logical
point-to-point trunk link or a LAG. The LAG balances traffic across the member links
within an aggregated Ethernet bundle and effectively increases the uplink bandwidth.
Another advantage of link aggregation is increased availability, because the LAG is
composed of multiple member links. If one member link fails, the LAG continues to carry
traffic over the remaining links.
Link Aggregation Control Protocol (LACP), a component of IEEE 802.3ad, provides
additional functionality for LAGs.
